Great in store, in today's class, we will introduced the rotate tool. This is a very important and basic tool that we will use most of the time. This help us to rotate lights, faces, and other geometries. Here we will learn how to use a tool to rotate 3D objects along any axis. Let's get started. We will use a cube to demonstrate the rotate tool. First, we create a cube, and then we group it. Now we select the rotate tool and we will see a protractor shaped cursor. We can move the cursor along until it's on the corner we want to use for the rotation. When the plane is perpendicular to a axis, the cursor turn red, green, or blue respectively. Next we use arrow keys to help us to choose the rotation axis. If we press the right arrow key, the cube will rotate along the red axis. The cursor will turn red, and it will appear perpendicular into the red axis. Now we can left lick to select the rotation axis. Then we will see the dark line from the points where we clicked. This dark line shows where the rotation starts. That is, when we want to rotate an object for a specific degree, SketchUp will start rotating from this line. It is important to note that, the length of the dark line does not affect the rotation. Now we left click again, and we can start rotating our object. Next, we will demonstrate how to rotate a surface. SketchUp will automatically detect the surface. No more vector as the rotation axis. So we need a new method if we want to change this simple rotation axis. First, select the surface and then, we'll click the rotation tool. We move the cursor to the desired position, and keep pressing the lap long spotter while we move to a new rotation axis. For example, if we want to red axis as the rotation axis, we move the cursor to red axis. Release the mouse button when the cursor become red, then we can rotate the plane. When we input the angle in the measurement box, sketcher will choose to rotate clock wise or counter clock wise. Depending on the mouse position. If you want the plane rotate a long the green axis, we move the mouse downwards and they will input the angle. The plane will rotate clock wisely. Similarly, if we move the mouse upwards and then input the angle, the plane will rotate counter clock wisely. What if we don't move the mouse? Let's try it. It rotates counter clock wisely. In today's class, we learnt the most of the function offered by the rotation tool. This tool works very well when we use the measurement box for the angle inputs, and also when we use the arrow keys to select the axis. We should remember that SketchUp has a default rotation, which is counter clock wise. And this one can be changed if you wish. Lets stop learning for now. Goodbye.
